This has enabled the creation of the first industry public chain, aimed at transforming platforms for property transactions, rentals, and investments. Were building a global, intermediary-free, decentralized smart real estate ecosystem, to ultimately achieve zero-cost property rentals and transfers. We aim to establish the worlds largest repository of property transaction and rental resources, allowing anyone to upload their property sales and rental information onto the public chain. As the first industry-specific public chain to transform traditional sectors, were creating a fully autonomous DAOs-based new business civilization with blockchain technology.
